Welding

CAUTION: Fuel tank and fuel lines must be drained and all vapors purged to ensure non-combustible mixture before any welding, brazing
or soldering.
If arc-welding is employed on the chassis or body parts or components which could be damaged by welding temperatures, these parts must
be removed or adequately shielded. Some examples are brake lines, fuel lines and fuel tank assembly, electrical wiring, electronic modules,
sensing and diagnostic module under the drivers seat and S.I.R. sensor under radiator support. To avoid electronic component damage,
disconnect battery (batteries); disconnect the negative cable first, followed by the positive. To reconnect cables; connect the positive first,
then the negative.
When welding low carbon steel side rails, crossmembers and brackets, emphasis is placed upon weld application techniques to avoid
stress risers that may adversely affect frame operating stresses. Note that some of the frame sections are made of high-strength-low-alloy
steel that could be adversely affected by heating due to welding. Also, prior to welding, the area to be welded and surrounding area must be
cleaned of all frame protective coating.
After welding, when parts are cool, carefully inspect wiring and electrical components for shorts or other damage which could draw
excessive currents and possibly cause an electrical system short when the battery is reconnected. Also, assure that the fuel systems and
especially the fuel lines are not damaged or distorted from the welding heat. Apply protective coating to areas where coating was removed.
Service and service replacement parts for your add-on systems may not be available from a GM dealer. Those installing aftermarket systems
should provide information as to where and how to obtain service.

Labels

All labels on the vehicle (any message applied to the
vehicle or vehicle component that informs, instructs, or
warns) must appear on the completed vehicle so the user
can read them easily and without obstruction.
NOTE: In order to be in compliance with FMVSS 208, no
other label shall be installed on the same side of
the sunvisor as the Inflatable Restraint Caution (Air
Bag) Label.
